Reference 3800 represents the mid-size iteration of the iconic Nautilus model. It was released in 1981, five years after the launch of the line as a downsized version of reference 3700; the goal of the company being probably to entice collectors who deemed the 42mm diameter of the original Nautilus excessive. It remained in production until 2006, during which the movement presented several evolutions. Early models feature caliber 335 SC without the quick set date feature through the crown. Such development was introduced in 1987, while keeping caliber 335SC. In 1992 a third generation was introduced featuring cal. 330 134, and finally cal. 330 194 was employed for the pieces made from 1997 to 2006, year of discontinuation.

The present piece is offered in extremely honest and attractive condition, but its true highlight is the highly sought-after and equally rare “Beyer” signature on the dial, indicating it was originally retailed by the celebrated Zurich-based retailer. According to our research, before the discovery of this fresh-to-the-market watch, only one stainless steel reference 3800 was known with the Beyer signature. The discovery of this example brings the total number of Beyer-signed ref. 3800 to two, making this a truly impossibly rare and exceedingly collectible wristwatch.
